ASME B16.5 Class 150 Gr1 Gr2 Gr7 WNRF Weld Neck Flanges Raised Face For Piping

Product Specification

Titanium ASME B16.5 Gr1 Gr2 Gr7 WNRF Weld Neck Flanges Raised Face For Piping Systems

1. ASME B16.5 Titanium Flanges

ASME B16.5 is a widely recognized standard developed by the American Society of Mechanical Engineers (ASME) for flanges and flanged fittings. This standard covers flanges for sizes 1/2 inch to 24 inches and pressure ratings from 150 to 2500 psi. Titanium flanges made in accordance with ASME B16.5 are used in applications where the exceptional corrosion resistance, strength, and lightweight properties of titanium are essential.

4. Advantages of Using Titanium Flanges 

Strong and Reliable Connection

• Enhanced Strength: The design of a weld neck flange, with its tapered neck that gradually transitions into the pipe, provides a strong, seamless connection. This tapering minimizes the stress concentration at the joint and ensures a smooth transfer of pressure and stresses from the pipe to the flange.
• No Stress Risers: Because of the continuous taper from the neck to the flange, the weld is less prone to the formation of stress risers, reducing the risk of failure under pressure.

Improved Leak Resistance

• Smooth Transition: The gradual transition of the weld neck flange ensures a smooth inner bore, which minimizes turbulence and reduces the likelihood of leaks. This smoothness is particularly important in high-pressure or high-temperature systems where leakage could have serious safety and operational consequences.
• Pressure Distribution: The design allows for better distribution of pressure, especially in critical applications where leaks would be hazardous or costly.

Ease of Maintenance

• Reusability: Weld neck flanges can be reused in many cases because the flange and pipe are welded together in a way that can be easily cut and re-welded if necessary. This is particularly valuable in systems where disassembly and reassembly might be required over the years.
• Less Likely to Fail: Due to the strong connection and high resistance to fatigue, weld neck flanges generally have a longer lifespan and require less frequent maintenance.

Versatility in Applications

• Variety of Pressure Ratings: Weld neck flanges come in various pressure ratings, making them suitable for a wide range of applications, from low-pressure to high-pressure systems.
• Adaptable to Different Sizes and Materials: They can be used in systems with different pipe sizes and materials, making them versatile for many industrial applications, including high-temperature, high-pressure, and corrosive environments.
• Variety of Welding Options: The design of the weld neck flange allows for different types of welding methods, such as butt welding or socket welding, depending on the specific requirements of the application.

Enhanced Durability in Harsh Environments

• Corrosion Resistance: Weld neck flanges are often manufactured from materials that are highly resistant to corrosion (e.g., stainless steel, alloy steels, or specialized coatings). This makes them ideal for use in harsh environments, including chemical plants, marine systems, and oil and gas pipelines.
• High-Temperature and High-Pressure Resistance: They can withstand high operating temperatures and pressures without compromising structural integrity, making them suitable for critical applications in power plants, refineries, and other industries where extreme conditions are common.

Reduces Fatigue and Stress

• Smooth Flow Path: The tapering design of the weld neck flange ensures that the pipe's stress and pressure are distributed evenly, reducing the risk of fatigue over time. This makes weld neck flanges ideal for high-stress applications where vibration, thermal expansion, or mechanical stress is a concern.
• Eliminates Stress Concentration: Unlike other flanges that might have sharp corners or abrupt transitions, weld neck flanges eliminate stress concentration points, making the connection more durable under fluctuating loads and conditions.

 Better Alignment and Fit

• Precision Alignment: The design of the weld neck flange ensures that the pipe and the flange align precisely, which results in a more accurate and stronger weld. This reduces the chance of alignment issues during installation and ensures a better overall seal.

6. Package of Titanium Weld Neck Flange

Titanium weld neck flanges are used in various industries including petrochemical, oil and gas, power generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing, textiles and others. Titanium weld neck flanges are packed to ensure that there is no damage during shipment. In case of export, standard export packaging is done in plywood box. Markings can be made as you require.
